just need to get creative... & patience helps too. you can get a normal wrench on the bolts but helps to have smaller hands & you will need to contort your arm some to move the wrench. or a smaller 1/4" drive rathcet & socket works too.

Thank you all. I used a combination of wrenches...gear ratchet, long wrenches, short wrenches. Bust knuckles, cuts and lots of patience. One thing that helped a whole lot was removing the hood. Made it so much easier.

The ratchet wrench worked when taking of the booster but on the new one the ratchet end was to thick to get it on. I do not have a grinder so I could not grind the sides down.

So it was mostly 1/4 turns for the 2 bottom bolts. Bench bled cylinder,,,everything back on now. Now onto brake bleeding.

BTW..bought units from the Right Detail...They told me that I do not have to do anything with the proportional valve when bleeding the brakes.

I had read here that the button had to be depressed while bleeding the brakes. They told me not to mess with it.
